Abstract The study investigates hydrogenation of CO 2 over mono- and bimetallic catalysts supported on biochar. In this reaction, iron–cobalt were shown to surpass monometallic iron cobalt in terms catalytic performance. optimal combination performance parameters was reached at an ratio 3 : 1. composition genesis the active phase Fe–Co catalyst identified, mechanism suggested for iron-dominated catalyst. Using biochar as a support found provide favorable hydrogenation.
The influence of polymer matrix on the activity composite material containing cobalt nanoparticles in Fischer-Tropsch synthesis was studied. It found that structure affects active centers formation. Magnetometry techniques situ and XRD confirmed presence metal its oxide phases which are different type effect.
Metal-carbon nanosystems consisting of nanodimensional bimetallic particles Fe- Co dispersed in a carbon matrix for the Fischer-Tropsch synthesis were studied. Prepared metal-carbon nanopowders samples characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning (SEM). It was shown formation FeCo nanoparticles with body-centered cubic structures started at 400 °C. have spherical form, mean size is 7 - 12 nm uniform distribution matrix. The nanosystem...
A series of solid solutions in the PdTe–PdBi system with general formula [Formula: see text]Bi x ([Formula: text], 0.5, 0.67) structure based on NiAs type were synthesized by a high-temperature ampoule technique. These compounds, along their parent binaries, PdTe and PdBi, tested as promoters for standard Co/Al 2 O 3 catalytic Fischer–Tropsch synthesis. It is shown that addition to catalyst increases both yield selectivity respect liquid phase. At same time, PdBi does not only improve...
Cu-Co-containing cellulose-based carbon composite materials (Cu-Co/Cel) were formed by a matrix isolation method.Using X-ray diffraction (XRD), transmission electron microscopy (TEM), infrared-Fourier spectroscopy (IR-Fourier spectroscopy), and non-isothermal research methods, the physicochemical properties of composites established.The catalysts are nanosized particles distributed in matrix, containing fragments system conjugated bonds (C=C-C=C) various lengths.Cu-Co/Cel active synthesis...
Carbon materials were formed by the hydrothermal carbonization of cellulose, which used as support for carbon dioxide hydrogenation catalysts (Fe/C and Fe-Mn/C). In presence these catalytic systems, CO2 conversion reached 50%. It is shown that manganese introduction into Fe-containing system significantly affects distribution gaseous С1-С4 products liquid С5+ hydrocarbons. Promotion leads to suppression methane formation an increase in proportion C2-C4 light olefins products, well...
Targeted synthesis of C/composite Ni-based material was carried out by the method matrix isolation. The composite formed with regard to features reaction catalytic decomposition methane. morphology and physicochemical properties these materials have been characterized using a number methods: elemental analysis, scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, temperature programmed reduction...
Methods for the formation of stable iron-containing suspensions that exhibit activity in conversion synthesis gas to C5+ hydrocarbons by Fischer-Tropsch method are proposed. By XRD and DLS methods it was determined Fe2O3 phase with a bimodal particle size distribution 50 295 nm results suspension drop thermolysis − gradual introduction active metal precursor solution into dispersion medium (mixture C19H40-C32H66).
